Improvement in carriage-lamps



NITED STATES PATENT-T FREDERICK O. CANNON, OF NEW HAVEN, UONNEOTIGUT.

IMPROVEMENT IN CARRiAGE-LAMPS.

Specification forming part of Letters Patent No. 162,898, dated May4,1875; application filed June 13, 1874.

To all whom it may concern:

Be it known that I, FREDERICK 0. CAN- NON, of New Haven, in the countyof New Haven and State of Connecticut, have invented a new Improvementin Carriage-Lamps; and I do hereby declare the following, when taken inconnection with the accompanying drawings and the letters of referencemarked thereon, to be a full, clear, and exact description of the same,and which said drawings constitute part of this specification andrepresent, in-

Figure 1, a side view and partial section; Fig. 2, a vertical section ofthe shell; Fig. 3, the blank bottom, back, and top; and in Fig. 4, atransverse section through the back or bottom.

This invention relates to an improvement in the manufacture of coach orcarriage lamps.

Heretofore the bottom, top, and back have been formed in secti0ns,soldered together, and

the lining has been set within, and soldered inside'the edge of thebottom or back. This construction necessitates many joints, which exposean unfinished appearance, in addition to the complex construction.

The object of this invention is to simplify and reduce the cost ofconstruction; and it consists in a coach-lamp body, the back, bottom,and top of which are in one and same piece, combined with a shank,having its head upon the inside of the'back, the stem projectingoutward, and a lining to cover said head, as more fully hereinafterdescribed.

, The bottom A, back B, and top 0 are out in a single piece fromsuitable sheet metal, and by suitable dies. The depressions from theinside are made to give the required external projection, as seen inFigs. 2 and 3.

Heretofore these projections have been made in separate pieces, andsoldered to the respective parts, which have also been made in separateor detached'pieces. This piece is then bent at the angles to the formseen in Fig. 2.

1n the back B a perforation, b, is made, through which the shank S ispassed, as in Fig. 2, the head f of shank upon the inside. where it issecured by solder. Over this the lining E is placed to hide the head.The plates which form the projecting rims of the cap are formed with ashoulder, a, around the edge, as seen in Fig. 1. The band 1) is formedfrom a strip of U-shaped metal, bent around the cap, one leg of the Ulying upon the shoulder a, and there soldered upon the un der side,which hides the solder from view and gives the cap the appearance ofbeing in one piece. The lining E, which is placed to cover the back andbottom, is formed the size of these parts, with a flange, d, to extendover the edge of the back or bottom. This lining is set in place, as inFig. 4, and the flange d soldered to the back or bottom, outside orbetween the flange d and the edge of the back or bottom,-as-the case maybe. This hides from View the means of securing the parts together, andgives to the interior or lining a much more finished appearance than theusual internal soldering.

I claim as my inventiou A coach-lamp body, the back, bottom, and top ofwhich are in one and same piece, combined with a shank, S, having itshead f upon the inside of the back, the stem projecting outward, and alining to cover said head, substantially as described.

FRED. O. CANNON.
